1. The laser and the power connection between connected and tighten the screw.

2. Please insert the power cord end before starting the power supply panel interface, the other end connected to 220 v power supply.3. Open the laser power switch, after a few seconds laser emitted.4. If you need to adjust the power, and could be controlled by adjusting the current of your laser lock when stable temperature control in the factory.5. If you want to access the TTL signal, need to first line plug on the received signal generator (5 VDC output), the red line to the positive, negative black line, select the appropriate frequency, and then insert the line after the laser power supply panel jacks, can obtain the laser modulation, signal plug pulled out, can restore the continuous laser.6. Need to shut down the laser directly close the laser power supply switch.Matters needing attention1. To prevent injury and person, please do not use laser direct illuminate in person especially on the human eye.2. The laser power, the power supply wire sealed with laser.3. Such lasers are more sensitive to temperature, when using must ensure good heat dissipation, as far as possible on the heat dissipation good metal plane.4. The laser can only receive 5 VDC modulation signal.5. Do not use for a long time, please place the laser in moisture-proof, anti-static place.6. Need to avoid severe impact damage to the laser.7. Remove and modified laser and power supply is not allowed while visiting, once the company shall not be liable for any losses incurred.

二、VB series laser instructions and matters needing attention

operating steps

1. Please send the power cord access before starting the 220 v power supply.2. After a few seconds, turning on the power supply of laser.3. If you want to access the TTL signal, need to first line plug on the received signal generator (5 VDC output), insert the line within the plug of the panel after laser, can obtain the laser modulation, signal plug pulled out, can restore the continuous laser.4. Close the laser directly off to the supply required.

announcements1. For your safety, please do not use laser direct illuminate in person especially on the human eye.2. Such lasers are more sensitive to temperature, when using must ensure good heat dissipation, as far as possible on the heat dissipation good metal plane.3. The laser can only receive 5 v TTL DC modulation signal.4. Do not use for a long time, please put the laser in moisture-proof, anti-static place.5. Avoid violent collision, otherwise it will cause damage of laser.6. Remove and modified laser is not allowed while visiting, which shall not be responsible for all the losses resulting from the company
